HEEL PRESS.

Applioationled pril 27, 1918. Serial No. 231,160.

fo all fr0/wm t may @office/Mz.:

Be it known that Enns'rUs E; YVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful improvements inHeel Presses; and l do hereby declare the following to be a full, clear, and exact description ofy the -invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention'relatesto heel-presses for maintaining pressure upon newly built heelpiles, composed of superposed lifts that are pasted together, during thesetting or drying of the paste, and is designed primarily as an improvement of the 4heel-press disclosed in applicants copending application, Serial No. 156,824, filed March 23, 1917, although the several features of the invention are also applicable to other machines of this general class. i The machine set forth in the above-indicated application is a power operated machine and comprises a rotatable carrier which supports a plurality ofheel-clamps to which heels are supplied by an auxiliary feeding device. The carrier and clamps are rotated step-by-step past the feeding station b means of a )ower drivingmechanism 1 7 which, under the control of 'the operator, is thrown into operation, and which, through the agency of a single revolution clutch, is automatically disconnected to permit the carrier to come to' rest. Power is also utiliz/.ed toY set and release the heel-clamps and to eject the heels therefrom after the paste has dried and the clamps are released. f

@ne of the objects of the present invention is to so modify, simplifyfand impro-ve the construction of the prior machine that it may be operated with a minimum expenditure of energy by the operator by means of a foot-treadle mechanism.

Another object is to provide an improved ejecting mechanism which shall operate with reliability and effectiveness to discharge the heels from the heel-clamps.

1n accordance with the present invention, one of the features thereof resides in a treadle mechanism and a co-operating double acting unidirectional ratchet dev ice whereby-the various instrumentalities of the machine may be operated with facility by foot-power supplied by the operator.

Another yfeature ofk the invention comprises an ejector for discharging heels from the clamps after the paste has set, and this ejector is lirst slowly advanced to gradually release the heelfrom its clamp in the event that excess paste causes it to adhere thereto, after which the ejector is rapidly projected to kick the heel free from the clamp and discharge it into a suitable receptacle.

The two features of the machine ust described, namely the improved operating treadle and vimproved ejector' mechanism, are the only features to be claimed in this application. Many other features of the machine to bev described, including the press actuating and heel ejecting devices in aspects and combinations other than as claimed herein, are novel and patentable, but claims the accompanying drawings illustrating the preferred embodiment of the invention.

ln the accompanying drawings, Figure l is a view, partially in side elevation and partially in section, of a heel-press embodying the presentrinvention, certain parts being broken away for the sake of clearness; Fig. 2 is a detail view showing part of the mechanism for opening .the heel-clamps; Fig. 3 is a partial plan view of the machine, a portion of one member thereof being'broken away for clearness; Fig. 4L is a plan View in section on the line ofFig. 1, showing the foot-power operating mechanism; Fig.k 5 is a side elevation. of a portion of the unidirectional ratchet device; Fig. 6 is a sectional view on the line 6-6 of Fig. 1, illustrating the ratchet device and cams operated thereby; and Fig. 7 is a plan view of a portion of the heel ejector, showing the parts in their outward projected position.

-Referring to the drawings illustrating the preferred embodiment of the invention, the machine is, in general, similar inconstruction and operation to the machine set forth in the aforesaid copending application, and comprises a supporting frame 10 upon Which the various parts of the machine are mounted; a carrier 12 rotatably mounted upon the supporting frame; a plurality of normally closed heel-clamps 14 disposed on the periphery of said carrier for severally holding freshly pasted heels under pressure until the paste has set; a retractor 16 and actuatingv mechanism therefor including a cam 18 for effecting the release of the successive heel-clamps at the ejecting and loading station; an operating` mechanism including a cam 2O for advancing the carrier and associated heel-clamps in stepi-by-step movement past the ejecting and loading station; a yielding bufer 22 and means for effecting its actuation including' an operating lever 24 for arresting the movement of the carrier as the several heel-clamps are brought into the ejecting and loading station; a combined gage and ejector 26 and operating mechanism therefor including a cam 2S for gaging the position of the heels as they are introduced into the clamps and for subsequently ejecting` them; and a main power mechanism for intermittently turning` the operating cams through a single revolution whereby the various parts of the machine are caused to function through a complete cycle of operation.

Except for the details of construction and operation of the ejcctinnmechanism and the main power mechanism, the machine is like that disclosed in the above mentioned copending application, and therefore only a briefI and general description of the common features of the machine will be given,

reference being had to said application for a more detailed. description, if desired.

The supporting frame 10 embodies a central pedestal 3() which supports an upwardly projecting stationary sleeve or tube 32. Rotatably mounted upon the tube 62 and resting upon the upper end of the pedestal 30 is a hub 34 which is provided with a. rigid arm 36 that is periodically reciprocated by suitable mechanism that is actuated by the cam 20. The outer end of the arm 36 carries a paivl 37 which is adapted to engage a series ot projections 38 upon the rotatable carrier 12 whereby the carrier is advanced step-by-step, as will be understood.

The carrier 12 comprises three annular members 40, 42 and 44, the intermediate member 40 being supported by radial ribs 46 from a hub that loosely su 1rounds the stationary tube 32 and rests upon the upper end of the intermediate hub 34. Thecarrier member 42 is disposed beneath the member 40 and is ixedly secured thereto by uprights 48, While the carrier member 44 is adjustably supported above said carrier member 40 by means of a series of threaded rods 50.

The respective heel-clamps 14 severally comprise an upper jan7 52 that is pivotally suspended from the upper carrier member 44, and a lower j auv 54 that is fixed at the upper end of a vertical rod 56 that is carried by and loosely mounted in the carrier members 40 and The rod is surrounded by a spring 58 that normally serres to hold the loiver clamp jaiv in its raised or clamping position. 'The loivcr end ofthe rod 56 is provided With a laterally projecting member 66 (Fig. 2) that is adapted to be engaged by the upper hooked end 62 of the retractor 16 when the heel-clamp is brought to the ejecting` and loading station.

In order to arrest the movement of the carrier 12 as it is advanced step-by-step to bring the heel-clamps 14 successively into position in which the clamps are released, the heels ejected, fresh heels loaded therein` and the clamps reset. the buffer 22 is periodically projected into the path of n'iovement of projections 38 hereinbefore mentioned.

xls the successive heel-clamps 14 occupy this position or station, the cam 18 functions through the mechanism associated therewith to cause the retractor 16 to hook over the laterally projecting members 6G of said clamps and to draiv down the lower clamp aivs 54 to release the clamps.

Assuming one of the heel-clamps to be released in the general manner just indicated, the next operation is to release the heel, if it chance to be stuck to the heelclamp, and to subsequently effect its ection or discharge. As already stated. one of thc features of the present invention lies in the improved type of ejecting mechanism and`r therefore, said mechanism will new be dcscribed in detail.

The ejector 26, which is adapted to perform the function of a gage for positioning a fresh heel as it is loaded into a clamp as Well as to kick out and discharge a dried heel, is located at the ejecting and load.- ing station and cooperates with the several heel -clamps 14 as they are successively brought to said station. rfhe actuation of the combined gage and ejector is in a substantially radial outward direction, and it has three salient positions.v one in which it is fully retracted to permit the rods 50 of the carrier 12 to pass as the carrier is advanced, one in which it acts as a gage and which is illustrated in dotted lines in Fig, 3, and one in which it is fully projected after having discharged a heel and in which it is shown in Fig. 7.

The ejector 26 is adjustably secured by means of a bolt-and-slot connection 66 to the xouter end of a horizontally and radially dis- Een l lll lill) is rigidly secured to a sleeve 76 that is in-l tegrally associated by means of a yole 76 with another sleeveSO, said sleeves being.

slidably mounted upon a horizontal guide rod 82. This lguide rod is n'iounted in stationaryposition in a block 84 which is fixed upon the upper end of the tube 32 and rotation of said sleeves upon said rod is prevented by an arm 86 that projects Afrom the sleeve S and is provided ivith an opento receive a second `guide rod 68 that is also lined to the block 84.

The inner end of the bar 68 is provided with a pin 90 that projects upwardly through a slot- 92 in the channel shapedplate 72, and the ejector 26 is normally maintained in its' extreme inner position with respect to the slide by means of a latch 94 that is pivotally mounted upon the pin 90 and theend of which is adapted to engage an angular shoulder 96 on the inner side of a lug 98 that is provided upon the channel'shaped member 72.l i

The latch 94 is Lbiased or held in its envgagging position by means ,of a spring' 100 having one of its ends secured to a pin 102 that is carried by the latch 94 and its other end suitably fastened to thek channel shaped member 72. The latch 94 is provided with a lug 106 that vprojects laterally beyond the side of the slide 70, by means of which the latch 94 is trippedin a manner tol be set forth. The pin 90 is straddled by a bifurcated end 110 of a lever 112 that is pivoted upon a. pin 114 that is carried by the sleeve 7 6. The other-end ofthe lever 112 is conf .nected to one end of a springr 116 having its opposite end iliastened to 'a' pin 116 that projects from the yoke member 78.' rllhe springY 116, therefore7 tends to actuate the lever 112 in such a direction as to project the ejector 26 outwardly Whenever the bar 66 is released by the tripping of the latch 94.

-Theslide 70 and the associated sleeves T 6 and 80 are actuatedl by means of an Lf shaped linlr 120. 'the angle of which is-pivotally connected to the slideOlby means of a pin 122. The L-shaped member 120 is provided with a short angularly disposed and rigid arm 124 that isadapted to cooperate with a cani surface 126 upon the lever 112 for the purpose of withdrawing the ejector 26 and setting' the latch94, as will be more fully set forth. The inner end of the l.- shaped member 120 is pivotally connected to an arm that isfixed on the upper end of a rock shaft 132 that `loosely projects through the stationary tube Thelovver end of the rock shaft 132 is provided With an arm (Figs. 1 and 4) `Which is connected by a universal joint 136 to a rod-138 having a universal connection 140 to the loijver end of an arm 142. This arm is integral with a hub 144 that turns on a shaft 146 that is suitably supported bv the frame of f upon 'a' shaft 154 that supported by the f machine frame.v

At this point7 it may be Wellto note that the retractor cam 18 and the carrier-advancing cam 20 are also fixed to the' quill 152. For purposes of the present explanation, it vvill merely be assumed that ysuit.

able mechanism is provided for rotating the cam-quill and the cams attached thereto, whereby the ejector 26 and all of the other mechanisms o-f the machine hereinbefore described are actuated. The particular mech; anism for rotatiine` the. yquill and cams constitutes anl important part of the present invention and Will be hereinafter described in detail.

n Returning to the description of the ejecting mechanism. the operation thereof Will new `be setfo'rth. Y Y

As shown in Fig". 3, onev of the heel-clamps 14zis at rest atl the 'ejecting and loading station` said clamp? havingbeenv released. the heel ejected and the' ejector 26 retracted to its gagging position, in which it is adapted to position the breast surface of the fresh heel that is introduced intothe clamp by the operator. after havinnloaded a heel into the clamp and in engagement with the gage, thequill 152 and associated cams 18`r 20 and 26are Vactuated through the agency of suitable niechanism to be later set forth.

As the cam 26 rotatesr its associated 1nechanism causes the arm 130 at the upper end of the rock-shaft 162 to be actuated in a counter-clockwise direction to cause the L shapedmember 120 to pull in the `slide 70 and associated sleeves 76 'and 80. As the angularity between the arm 13() and themember decreases, the short arm 124 of the L-shaped member 120 engages the cam 126 on the lever 112 and forcesfin said lever and associated ejector bar 66 and ejector 26 against the action of the spring 116 until the end of the latch 94 drops into the angular notch or Ashoulder 96 in the lupi 96j. whereby the ejector 26 is set andlatched to the movable slide 70. The continuation of the counteiclockivise movement offthrI arm` 130 effects a further retraction of the slide .70 and the ejector 26e .that is latched thereto, until said ejector is Withdrawn: to its extreme inner position.' After the ejector 26 has been Withdrawn from the 'clamp7 the @am 18 and itsv associated `mechanism causes the retractor 16 to permity the clamp to close upon the fresh heel and place it under pressure.

The carrier 12 is then advanced by means of the cam and the carrier-operating mechanism that is actuated thereby to bring f sition. after which the continued rotation of the cam 28 actuatesthe rock shaft 182 and upper arm 130 in a clockwise direction. In l so doing, the slide 70 and the ejector 26,

"'55 which is set and latched thereto, are moved Iio outwardly, bringing the latter into engagement with the heel that is in position in the heel-clamp that has just been released. As the'ejector is thusactuated, the heel, which may have adhered to the clamp by reason of the excessv of paste employed, is released therefrom.

At this point in the operation, the toggle formed by the arm 130 and the member 120 has been straightened out to such an extent that the inner side ofthe member120 is brought into engagement with the lug 106 on the latch 94. Thereupon, the latch is forced out of engagement with the angular shoulder 96 of the lug 98 on the channel member 72 and the spring 116 suddenly racts upon the lever 112 to cause the bar 68 and the the ejector 26 to be rapidly projected in an outward direction to kick the heel out of the clamp and free from the machine. The positions of the parts of the ejecting mechanism under these conditions are shown yin Fig. 7.

The partial retraction ofthe ejector 26 to its initial gaging position. as illustrated in Fig. 3, is then effected bv the cam 28 through the mechanism hereinbefore described, it being understood that duringthis movement, the spring 116 is being placed under tension at the same time that the slide and the ejector 26 are being withdrawn. The cycle of operation is then completed and the machine comes to rest.

From the foregoing description of the ejecting mechanism, it will be understood that any heels that have adhered to the heel-clamps are first loosened by the positive operation of the mechanism under the control of the cam 28, after which the ejector 26 is caused to suddenly inopel the loosened heel from the clamps by means of the auxiliary spring actuated device above described.

Having set forth in detail the construction and operation of the improved ejecting mechanism` the other feature of the invention which pertains to the means for supplying power to the cam-quill and operating cams, and which constitutes a foot-power treadle mechanism operating in conjunction with a double-acting unidirectional ratchet device, will be described.

In the foregoing description, it has been assumed that suitable means for rotating the cams 18, 20 and 28 upon the cam-quill 152 is provided. The particular means for effecting this operation. and which so modified the construction and operation of the heel-press of the prior copending application that it may be effectively operated by foot-power with a minimum expenditure of energy, comprises gear wheel 160 that is integrally associated with the quill 152 and which cooperates with a gear wheel 162 of twice the diameter. This gear wheel 162 is provided with a hub 164 by means of which it is rotatably mounted upon the shaft 146. Fixed to the hub 164 of the gear wheel 162 is a disk or ratchet member 166 having a plurality of notches 168. 170. 172 and 174 provided in its periphery and disposed in pairs diametrically opposite one another. The notches 168 and 172 are located on one side of the disk and the other pair of notches 170 and 174- on the opposite side thereof.

In order to actuate the ratchet 166 and associated `gear wheel 162 step-by-step in a single direction, a plurality of pawls 176 and 178 are provided, which are adapted respectively to cooperate with the notches 168 and 1172 on one side of the disk, and with the notches 170 and 174 on the opposite side thereof. The pawl 176 is pivotally mounted upon a pin 180 that is carried by and projects between arms 184 and 186 that are respectively loosely mounted upon the shaft 146 and upon the hub 164 of the gear wheel 162, while the pawl 178 is similarly mounted upon a pin 188 that projects between arms 190 and 192 that are respectively loosely mounted upon the hub 164 and upon the shaft 146. A. spring 194 is connected to the pawl. 176 and the arm 184 and tends to maintain said pawl in engagement with the periphery of the ratchet or disk member 166. while the spring 196 performs a similar function in connection with the pawl 178.

Pivotally connected to the associated arms 184 and 186 that carry the pawl 176 is a link 198, the upper end of which is located between said arms and is pivotally mounted upon a pin 202 that is carried thereby. The upper end of a link 204 has a similar pivotal connection upon a. pin 206 to the associated arms 190 and 192. The several links 198 and 204 are curved outwardly in opposite directions, and the lower ends thereof are respectively pivotally connected to a foot-treadle 208 by means of pins 210 and 212. The foot-treadle 208 is pivoted at one end to the machine frame 10 upon a stud 214, and the free end thereof constitutes a pedal 216 upon which the operator steps in operating the machine.

The treadle 208 is normally held in its fore the gear wheel 162,

raised position by means of a heavy compression spring 218 which actsthereon through the medium of a chain 220. The spring 218 surrounds a cylindrical sleeve or pipe 222 that is conveniently screwed into a plate or bracket 224 which is mounted upon the machine frame, and disposed within said sleeve or pipe is a slidable rod 226, the outer end of which is provided with a washer 228 and adjusting nut 230 against which the end of the spring 218 abuts. rilheinner end of the rod 226 is connected to the chain 220 which projects through an opening inthe plate or bracket 224; and passes over a loose pulley 232 that is held on the shaft 154 by means of a collar 284. The other end of the chain is attached to the treadle 208 by means of a pin 236.

Assuming the treadle mechanism to occupy its raised normal position, the operation of the treadle mechanism, ratchet device and the several cams and their associated operating mechanisms is effected in the following manner lhen the operator has placed a fresh heel into an open clamp at the loading station, he steps upon the footpedal 216 of the treadle 208 and forces it into its depressed posit-ion. In so doing, the pawl 178 drops into one of the notches 170 or 174 on the remote side of the ratchet disk 166 and, as the curved link 204: is moved downwardly, said pawl 17 8 effects the clockwise rotation of the disk 166 and associated gear wheel 162. As the gear `wheel 162 is actuated through substantially a quarter turn, the cooperating gear wheel 160, and therefore the quill 152 and associated cams 18, 20 and 28, are rotated through a-half revolution, whereby the various actuating mechanisms `of 4the machine are partially operated in the manner already described. The positions of the part-s of the foot-power treadle mechanism and ratchet device, when the treadle 208 occupies its depressed position, are as shown in Fig. 1. Durin(Y the depression of the treadle 208, the power spring 218 is compressed, whereby energy is stored therein which is utilized to return the treadle 208 and the mechanism connected therewith to its initial position when the operator releases the treadle.

As the treadle 208 is raised by the spring 218, the pawl 176 which lies in one of the notches 168 and 172 on the near side of the ratchet disk 166 causes said disk, and thereto be actuated through another quarter turn in the same direction as before, the positions of theM parts of the ratchet device being illustrated in Fig. 5 in a partially raised position. The actuation of the gear wheel 162 causes the cooperating gear wheel 160 and the associated quill 152 and cams 18, 20 Aand 28 to be rotated through a half turn.` whereby the various mechanisms of the machine are andremain so until the operator again sup- V plies power to ther machine treadle mechanism.
